Time Change in US: When Do Clocks Go Back in Illinois?

Click For Summary

Discussion Overview

The discussion revolves around the timing of the clock change for Daylight Saving Time in the United States, specifically focusing on Illinois. Participants share their experiences and thoughts regarding the implications of the time change, including comparisons with other countries and regions.

Discussion Character

  • Exploratory
  • Debate/contested
  • Meta-discussion

Main Points Raised

  • Some participants confirm that clocks in Illinois will go back on November 4, 2007, at 2:00 AM.
  • Concerns are expressed about the impact of the time change on older operating systems, particularly Windows 2000 and XP, which may not handle the adjustments smoothly.
  • There is mention of a change in congressional decisions affecting the timing of the clock change, with some participants noting that the switch used to occur earlier.
  • Participants discuss the differences in Daylight Saving Time observance across the U.S., highlighting that some states, like Arizona and Hawaii, do not observe the time change.
  • Confusion arises regarding the Navajo Nation's observance of Daylight Saving Time, with participants sharing personal experiences related to time changes in Arizona.
  • International perspectives are shared, with participants noting that countries like New Zealand and South Africa have different practices regarding clock changes.
  • One participant mentions the practical implications of clock changes in a lab setting, where machines automatically adjusted their clocks.

Areas of Agreement / Disagreement

Participants generally agree on the date and time for the clock change in Illinois, but there are multiple competing views regarding the observance of Daylight Saving Time in different regions of the U.S. and internationally. The discussion remains unresolved regarding the implications of these differences.

Contextual Notes

Participants express uncertainty about the historical context of Daylight Saving Time changes and the varying practices across different regions, which may depend on local legislation and cultural practices.

Does anyone know when the clocks go back in the United States (specifically Illinois, if that make a difference). Here in the UK, we put them back in about an hour, but it suddenly dawned on me that you lot may not do the same as us! (I presume you do put the clocks back?!)

Ahh, ok. Cheers, Astro!
 
I'm not looking forward to it, because we use older Win2K OS's well as XP. Actually, XP SP2 was more of a pain in the a$$ to deal with - the adjustments that we supposed to work smoothly - didn't.

Anyway, I get a new box next week as my main office PC is in its death throws with a failing motherboard or RAM chipset. I think the HD's are still OK, but the OS is currently unstable.
 
We USED to switch this weekend, but some folks in Congress seemed to think we didn't need that extra hour of sleep yet.

Hey, at least it's only one week. I presume you put your clocks forward a week after we did too!

Edit: Hey, PF is clever.. it just changed the time back for me!

Nope, we put them forward way before you did. They extended the entire duration of daylight savings time at both ends this year. I've already been waking up an hour later though...my body is ready for the time to change and doesn't care what the clock says.
 
Damn! Its 4:16 or something which makes it 3:16 now. there's not much point in me having an extra hour of sleep being up at this time. :cry:
 
Clocks changed a few hours ago here (uk). Its 3:35 (4:35) here now. Either way i should not be up...

Not all the US has daylight savings time. Some places do not move their clocks back at all, while others do.

For the U.S. and its territories, Daylight Saving Time is NOT observed in Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands, the Commonwealth of Northern Mariana Islands, and Arizona . The Navajo Nation participates in the Daylight Saving Time policy, even in Arizona, due to its large size and location in three states.

I used to live in Arizona. I had no idea the Navajo followed daylight savings. How confusing must that have been?

I'm from AZ. No clock changing here!

Clocks here (New Zealand) were set back nearly a month ago now. South Africa doesn't put their clocks back... its so confusing... :o

I was in the lab today one hour longer since all the machines changed the clocks one hour backwards. Canada is also changing its clock on Nov 4 now (at least in Toronto)

You set the clocks back this time of year too? Isn't that a bit counterintuitive considering you're in the Southern hemisphere? Shouldn't you folks be switching your clocks the other way now? :confused:

You have no idea... The Hopis that have their nation in the middle of the Navajo Nation follow Arizona time so in the course of an hour (driving from the North) one can go from Daylight Time to Standard Time to Daylight Time to Standard Time.
